Vista HP 64-Bit hard lock when using AVAST

Avast Free Antivirus / Premium Security
1

Avast has always worked perfectly on my system but since the Vista HP 64-Bit update recently (Not installed Vista SP1 yet and no change to system other than the MS recent update), Avast now stops during the Windows system virus check on C: requiring a PC reset as a total freeze happens. (Asus P5N32-E SLI Plus, 4Gb Corsair, Raptors, 1xEGVA 8800 GTS 640Mb, Toughpower 850W)

Anybody else have this problem or an idea how to fix would be appreciated please.

It was one of the WOW series of files but I will run Avast again and note the actual file name.

Typical! Since the Vista update, on the 13th February, I ran Avast twice and both times it locked the PC requiring a reset. I have just run my same scan (C: D: and E: partition) twice and once, just on the Windows dir., and perfect - no lock up! The only difference with these scans was I had run Windows Defender on a quick scan before I rechecked Avast but I can’t see that would have made any difference.

I will report back if I have any further lock-ups and thanks for your interest.
